3D pong with video paddle tracking

Introduction

POTION is a motion-controlled game system that allows two players to battle head-to-head or one player to compete against AI for ultimate ping pong glory. For the two-player setup, two video feeds from consumer digital cameras are each separately fed into a pair of slave DE2 boards. These inputs are primarily used to detect objects held in players' hands to represent paddles. See:
